What You'll Learn
Diesel fuel is a cheap, effective cleaner
Diesel fuel is a cheap and effective cleaner for certain applications. It is particularly useful for cleaning mechanical parts, such as engines and machinery, and can be used as a degreaser and carbon deposit remover. Its high flash point makes it one of the safer hydrocarbon-based cleaning options, and it is less likely to cause accidental fires or explosions compared to gasoline.
Diesel fuel is also a good option for those looking for a cheap cleaner. It can be purchased in large quantities at a relatively low cost, making it an economical choice for those who need to clean multiple parts or deal with heavy grease and grime.
One of the key advantages of using diesel fuel as a cleaner is its ability to prevent corrosion. The oily residue left behind by diesel can act as a lubricant and protect metal parts from rusting, at least in the short term. This is especially beneficial for steel parts, which are prone to rusting if allowed to air-dry.
However, the oily residue left by diesel fuel can also be a disadvantage. While it may contribute to lubrication, it can attract dirt over time, leading to a buildup of abrasive grime. Additionally, the strong and persistent smell of diesel fuel is often cited as a significant drawback, with some users finding it difficult to remove the odour from their hands, clothes, and work areas.
To mitigate the smell, some people use exhaust hoods or similar setups to vent the fumes. Others opt for less odorous alternatives, such as kerosene, which is cheaper and just as effective as diesel but with a milder scent.
In conclusion, diesel fuel can be a cheap and effective cleaner, especially for mechanical parts and engines. Its high flash point and corrosion-resistant properties make it a safer option than gasoline, and its lubricating qualities can be beneficial. However, the strong smell and oily residue are significant drawbacks that users should consider when deciding whether to use diesel fuel as a cleaner.

It's oily residue can be beneficial, preventing rust
Diesel fuel is an effective cleaner that can be used to remove carbon deposits and leave parts shiny. It is particularly useful for cleaning engine parts, as it can prevent rust by leaving a thin layer of oil on the parts. This oily residue can be beneficial in preventing rust, especially on steel parts.
One user recalled how their father used to clean car engine parts with diesel, soaking them overnight in diesel fuel and then cleaning them with a brush in a bucket of fresh diesel. This method effectively removed carbon deposits and left the parts clean and shiny. Diesel fuel is also one of the safest hydrocarbon parts cleaners in terms of flashpoint reference.
However, diesel fuel has fallen out of favour in commercial and home shops due to its strong smell and the oily residue it leaves behind. Some users have expressed concerns about the smell of diesel fuel, which can linger on clothes and hands even after the cleaning process. This has led some people to prefer other solvents, such as kerosene, which is less odorous and leaves less residue.
To mitigate the smell of diesel fuel, one user suggested using an exhaust hood over the tank. Another user recommended deodorised kerosene, which is sold as "lamp fuel" and is slightly less odorous than diesel. While diesel fuel may not be the most popular choice due to its smell and residue, its oily residue can still be beneficial in preventing rust on metal parts.
It is important to note that while diesel fuel can be effective in preventing rust, it may not be suitable for all applications. For example, one user questioned its desirability for engine parts that are not frequently disassembled. Over time, the oily residue could attract dirt and result in an abrasive mess. Therefore, it is recommended to consider the specific application and the potential benefits and drawbacks of using diesel fuel as a parts cleaner.

It is safer than gasoline, but still flammable
Diesel fuel is a good parts cleaner, and it is safer than gasoline but still flammable. It is one of the safest hydrocarbon parts cleaners in terms of flash point, and it will not explode if exposed to a flame. However, it ignites under pressure, so it is important to exercise caution when using it.
Diesel fuel is an effective and cheap cleaner. It can be used to soak parts, and it leaves a little oil on everything, making it easier to clean later. It also helps prevent corrosion for a short period. However, it is important to note that diesel fuel has a strong and lingering odour, which can be difficult to remove from clothes and hands. This has led to a decrease in its use, with many opting for water-based or commercial alternatives.
When using diesel fuel for cleaning, it is important to follow it up with a dish soap and water rinse to remove any residue. Additionally, it should not be disposed of down the drain, as it can cause environmental harm.
Compared to gasoline, diesel fuel is a safer option for parts cleaning. Gasoline is highly flammable and has been associated with accidents and explosions due to its fumes. However, diesel fuel still poses a flammability risk, and it is important to take the necessary precautions when using it.
Overall, diesel fuel is a viable option for parts cleaning, especially for those seeking a cheap and effective solution. However, its flammability and strong odour are important considerations, and users should prioritise safety and proper disposal methods when utilising this cleaner.

It has a strong, lasting smell
Diesel fuel is an effective cleaner for parts. It is particularly useful for removing carbon deposits and other dirt and grime from engine parts. However, one of the main drawbacks of using diesel fuel as a parts cleaner is its strong and lasting smell.
Diesel fuel has an obnoxious smell that can be difficult to get rid of. The odour tends to linger on clothes and hands, even after the cleaning process is complete. This has led to fewer people using diesel fuel for parts cleaning, opting instead for commercial solvents like naphtha or mineral spirits.
To mitigate the smell, some people use an exhaust hood over the cleaning tank to vent the fumes. Others choose to use less pungent alternatives, such as kerosene, which is similarly effective as a cleaner but has a less intense odour. Kerosene is also available as deodorized kerosene, which is even milder in terms of smell.
While diesel fuel may be useful for occasional parts cleaning, the strong and lasting smell can be a significant drawback, especially for those who are sensitive to strong odours or work in enclosed spaces. The lasting smell of diesel fuel can also be unpleasant for those who want to avoid having the odour permeate their workspace or clothing.
For those who can tolerate the smell or who have adequate ventilation, diesel fuel can be a viable option for parts cleaning due to its effectiveness in removing grease and dirt. However, for those seeking a more pleasant or odourless cleaning experience, alternative solvents may be preferable.
